Embodiment Construction

[0039] figure 1 The lower plate of the airbag unit 1 is shown to be snap-fastened to a frame part 2 , such as a steering wheel hub or a contact bridge fixed to the steering wheel. For this purpose, the airbag unit has snap-in hooks 3 on its underside, to which snap-in hooks 3 are associated plastic snap-in clips 4 on the frame part 2, said snap-in clips 4 having cylindrical projections 13 which are pivotable The bearing 5 ( figure 2 )middle.

[0040] Depend on figure 2 and image 3 It can be seen that the plastic snap-in clip 4 has a deformable part 6 and a pivotable part 7 . The plastic snap-in clip 4 is mounted in such a way that the parts 6 and 7 protrude into the opening 8 of the frame part 2 . The side 10 of the deformable portion 6 associated with the stop 9 of the opening 8 extends obliquely from the bearing 5 in the direction of the stop 9 . The side 11 of the pivotable part 7 associated with the snap hook 3 extends obliquely from the bearing 5 in the direction...

Abstract

The invention relates to a device for snap-fastening an airbag unit in a subassembly of a motor vehicle, especially in a steering wheel of a motor vehicle, snap-in elements that are associated with each other being provided on the airbag unit and on the subassembly of the motor vehicle. In order to be able to snap-secure an airbag unit both to a plate-shaped subassembly and to a subassembly having a lateral wall, at least one snap-in hook (3, 22, 40) is provided on the airbag unit (1, 21, 41) or on the subassembly of the motor vehicle (2, 24, 38), at least one pivotable plastic snap-in clip (4, 17, 17a) being associated therewith on the other subassembly. The snap-in hook (3, 22, 40) engages with said clip in at least one section thereof when in the snap-in position.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for snap-fastening an airbag unit in a component of a motor vehicle, in particular in a steering wheel. Background technique [0002] Devices for fastening airbag units in motor vehicle components are known. For example, an airbag module is known from EP 1 314 621 A1, in which the airbag unit has elastically deformable snap hooks on its outer side which can engage behind latch portions on the inner side of the airbag housing side wall. In this case, the airbag unit is introduced into the airbag housing from above. As soon as the snap hook reaches the area of ​​the latch section, the snap hook slides along the latch section and deforms elastically in the direction of the side wall of the airbag unit. On reaching the end position of the airbag unit in the airbag housing, the snap-in hook springs back and engages under the latching part of the airbag housing. Thereby, the airbag mod...
